Synthesis and characterization of donor-acceptor oligothiophenes
(2005)The field of organic conductors is multidisciplinary in nature. This thesis introduces and characterizes new conducting materials based on heterosubstituted oligothiophenes. Substituted bithiophenes, terthiophenes, and ... -
Synthesis and cytotoxic activity of diosgenyl saponin analogues
(2008)Saponins are naturally occurring glycosides that are widely distributed in the plant kingdom and lower marine organisms. Saponins consist of a carbohydrate chain attached to either a steroid or triterpene aglycone. Diosgenyl ... -
Synthesis and electrochemical study of Pd- and Pt- based nanostructured materials
(2011)We are currently facing climate change and global warming effects due to the emission of greenhouse gases from our existing energy sources. Proton exchange membrane fuel cells are one of the most efficient alternatives ... -
Synthesis and electrochemical study of Pt- and IrO2-based nanostructured materials
(2006)With ever increasing awareness that our environment is being ravaged at an alarming rate and the very seriously high rate of diabetes, there has been much research into understanding, controlling and reversing these ... -
Synthesis and electrochemical study of PtIr nanomaterials
(2008)Nanomaterials have a number of unique chemical and physical properties and have attracted tremendous attention due to their potential for applications in a variety of areas including fuel cell and biosensor development. ... -
Synthesis and reactivity of enediynes
(2004)The discovery of a class natural products with anti-cancer properties, the enediynes, has stimulated interest in their research. Due to their cytotoxicity, these compounds are not feasible for use in cancer treatment, ... -
Synthesis of alginate neoglycolipids / by Rongsong Xu.
(2007)Innate immunity, one of two arms of the immune system, can provide more rapid defense mechanisms than adaptive immunity in human immune defense systems. The innate immune system recognizes invading pathogens by binding a ... -
Synthesis of model compounds related to the tetranortriterpenes
(1971)In this thesis some preliminary studies have been described, which were aimed at the synthesis of compounds in which a 3-substituted furan is attached to a 6-lactone ring so as to yield structures of the type observed ... -
Synthesis, characterization and photocatalytic application of TiO2 nanosized particles / by Dongliang Liao.
(2007, c200)In this thesis, effects of surfactant composition and concentration on shape, size, zeta potential, and photocatalytic activity of TiO2 nanosized particles are reported. Spherical, cubic, rod, ellipse and leaf-like shaped ... -
Synthetic approaches to five-membered heterocycles containing both ring and side-chain phosphorus atoms
(1983)A brief review of the importance and variety of symmetrical and unsymmetrical bisphosphines is given and the possible theoretical and synthetic value of bisphosphines in which one of the phosphorus atoms is included in ... -
Synthetic approaches to new heterocycles containing two phosphorus atoms
(1971)Reactions involving nucleophilic attack of tertiary phosphines and related compounds upon acetylenic systems have been reviewed and the literature has been covered to the end of 1970. In an extension of some of the ... -
Synthetic studies on chaksine
(1970)This thesis is concerned with the preliminary studies in the synthesis of a monoterpenoid alkaloid, chaksine. Diethyl methylmalonate was alkylated with 1,3-dibromo propane to give 2-(3-bromopropyl)-2-methylmalonate. ... -
Synthetic studies on chaksine
(1981)This thesis is concerned with the studies in the synthesis of a monoterpenoid alkaloid, chaksine. Ethyl 2-n~butyl-4-bromoacetoacetate (11) was treated with sodium azide to give ethyl 2-n-butyl-4-azidoacetoacetate (12), ... -
Synthetic studies on slaframine
(1980)Thjs thesis is concerned with the prelIminary studies in the synthesis of an indolizine alkaloid, slaframine. A Wittig reaction of 3-carbethoxypropyltriphenylphosophonium iodide (43) with 4-pentenal (44) gave ... -
System identification and control of a flexible manipulator
(2000)The Observabilty Range Space Extraction (ORSE) algorithm used to identify a an initially overparameterized discrete-time state-space model for a single-link flexible manipulator. A controller named PDPC is designed to ... -
